// Jeremy Meredith, Wed Nov 24 12:22:32 PST 2004
// Expression-language specific tokens are in a new,

//
// Jeremy Meredith, Mon Jun 13 15:46:22 PDT 2005
// Made ConstExpr abstract and split it into multiple concrete
// base classes. Made FunctionExpr and MachExpr use names
// instead of Identifier tokens. These two changes were to
// remove Token references from the parse tree node classes.
